HAND-OPERATING EYELETING-MACHINE.

Specification of Letters Patent.

,Patented Oct. 13, 1908.

Application `filed. July 21, 1905. v Serial No. 270,676.

To all whom 'it may concern.'

Be it known that I, JONATHANLEE KNIGHT, a citizen of the United States, residing at Kansas Oity, in the county of Jackson and. State of Missouri, have invented certain new. and

useful Improvements in Hand-Operated Eyeleting-Machines, of which the specification.

This invention relates to `parallel jaw punching and eyeleting tools, and has for its object to roduce a device of this character by which oles and eyelets of different sizes may respectively be punched and set.

A further object is to produce a device of this character of simple, strong, durable and chea construction.

With these objects in view the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which- Figure 1, is a view partly in side elevation and partly in central longitudinal section, the tool being open. Fig. 2, is an edge view with the tool closed. Fig. 3, is a section on the line X-X of Fig. 1. Fig. 4,-is a section on the line Y-Y of Fig. 1. Fig. 5, is a plan view of the head end of one of the handles. Fig. 6, is a detail side view of the punch.

In the said drawings, A indicates a air of levers formed preferably of sheet meta rovided with what are usually known as hollow handles and bifurcated heads, saidl heads extending inwardly and forwardly at an angle to following is a the handles with the bifuications in the plane j of the grooves of the latter.

Each head is proyided at the rear end of the inner edge of one of its branches or arms with an offset A projecting inwardly ofthe corresponding edge of the companion branch or arm. The heads are also provided forward and outward of said offsets with holes 2 through which a pivot 1 extends to connect the levers together, it being noted by reference to Fig. 4, articularly, that the offsets A of the hand es are disposed at opposite sides of the pivot from each other and by reference to said figure and Figs. 2 and 3, that the arms or branches equipped with said offsets are fitted against arms or branches of the lever.

B indicates a pair of similar parallel jaws arranged at opposite sides of pivot 1, each having its rear end projecting into the hollow porthe inner sides of the other i tion fitting in the bifurcated head of the other handle and pivotally connected to the latter by a pivot pin 3, said pins extending parallel with pivot 1 and engaging holes 4 in the said heads. The rear ends of the j awsB terminate in flat lugs B3 disposed op osite each other in the plane of the longitudlinal center of the handles. F indicates parallel links extending transversely of the jaws at the outer sides of the flat lugs B3 thereof, each link being pivoted at one end by a pin 5 to a different lug B3 and at the opposite end to a pin 7 projecting inwardly from the offset A of the handle to the head of which the companion jaw is pivoted, the arrangement being such that the inks are spaced apart a distance substantiallyBcorresponding to the thickness of the ugs 3.

In the construction thus far described the movement of the lever handles toward each other results in a movement of the jaws toward eachother in parallel relation, a coil spring E between the arms or branches of the heads and between the links F and pivot 2 resisting the movement described and serving to impart opposite or opening movement to the tool.

Each jaw is provided in transverse alinement and forward of the pivot 2 with a guide passage 4 and is also equipped at its outer side with an arm B, said arm curving outward and forward from the jaw contiguous to.ilat lugs B3 and extending forward to a point beyond the contiguous guide passage 4 to provide a mouth 6, for a purpose hereinafter explained, the arms B having passages 8 alined with passages 4 and forming female dies to co erate with the male dies or punches O, C, which as shown clearly in Fig. 6 arepreferably of different diameter so as to punch holes of different sizes, it being understood of course that the female dies are likewise of variable size as shown in Figs. 1 and 2.

The dual punch above described. is provided with a rigid stem C which extends rearwardly through the pivot 1, which thus acts to prevent endwise movement of the punch, lateral movement being prevented because the latter is continuously engaged with guide passages 4.

B2 indicate tenons projecting forward from the front end of the jaws, and rotatably adjustable thereon are eyeleting blocks D, set

of one of the handles and its front end screws D being mounted in blocks D to engage the tenons and clamp said dies in the desired relation, that is with the male die 9 of one facing the female die l() of the other. It is preferred that each :block shall be equipped with a male and female die and that such dies shall -be-.of diiferentdiameters so as to accommodate the different sized holes produced by the dual punch.

In practice paper, leather or other material is slipped into the proper vmouth 6, and the handles brought together to punch a hole in such material. A rivet may then kbe inserted in the material and placed between the correspondingly sized dies 9 and l0, the levers being Aagain operated to set the rivet. ln the movementof the `handles toward each other, the links move oppositely endwise until each laps lug 'B3 at the opposite side from the link pivotally attached to each lug, and to accommodate this tmovement of the links said lug-s are disposed centrally -of the jaws B as hereinbefore stated.

In Fig. 4, the tool is open and for this reason the fiat lugs B3 of the aws are disposed outward ofthe contiguous end of the link carried by the lug of the companion jaw, and it will be readily seen by reference to Fig. 4 that when the jaws are caused to approach the upper link F will pass above the right hand lug B3 and the flower link below fthe'lefthand lug B3.

From the above description it will be ap parent that lhave produced a tool possessing the features of advantageenumerated as desirable and I wish it -to be `understood that I do not desire 4te be-limited lto the exactdetails of construction shown and described as -obvious modi'iications will suggest themselves to -one skilled in lthe art.

vrI-laving thus described the invention `what Iclaim as new and desire to secure lby Letters Patent, is

l. A tool of the'charaoter described, comprising a pair of crossed levers consisting-of handle and bifureated '-head portions, and each provided with a "lug projecting inwardly from its handle portion, a pivot connecting said levers at their crossing points through said head portions, a pair of 'longitudinal jaws at opposite sides of the pivot with their front portions fitting in the bifurcated heads of different levers and their rear ends 'proj ecting into the hollow handles of the other levers and provided centrally at such ends `with flat lugs, a link Ipivotally connecting the AYHat lug of oneofsaid aws with the inwardly proj-ectingilug of the lever in the lbifurca-ted lhead of which the other jaw is pivoted, a similar link pivotally connecting the flat lug of the other aw with the fiat lug of the other handle, and a spring for holding said jaws yieldingly apart.

2. A tool of the character described, coinprising a pair of crossed levers consisting olY handle and bifurcated head portions, and

each provided with a lug proj ectingfinw ardly from its handle portion, a pivot connecting said levers at their crossing points through said head portions, a pair of longitudinal jaws at opposite sides of the Ipivot with their front portions fitting in the bi'lureated heads of different levers and their rear ends projecting into the hollow handles of theother levers and provided centrally at such ends with fiat lugs, a link pivotally connecting the iiat lug of one of said jaws with `the inwardly projecting lug of the lever in the bi'lurcated head of which the other jaw )ivoted, a similar -link pivotally connecting tlhc `[lat lug of the-other jaw with the flat `lug of the other handle, and a spring` pressing 'outwardly against-said aws and arranged between .the pivot of the levers and said links and prevented by said pivot and links from slipping out of operative position.

3. A tool of the character described, coinprisingva pair of crossed levers, consisting o1'V handle and bifurcated head portions, a pivot connecting said levers at their crossing points through -said head portions, a pair of longitudinal jaws at opposite sides of the iivot, each with its Irear end projecting into tlhe bifurcation of one of lthe 'levers and its `front end iittingin the frontend of the bifurcation of the other lever, one aw having'a ktransverse passage forward of the pivot, an arin rigid with and outward ofthe jaw provided with -a passage and provided with an alincd passage or -female die, -iivots Iextending through the jaws at the front ends of the levers, flat lugs at `the rear-ends of the jaws, a pair of transversely extending parallel and overlapping links occupying the bifurcations of the levers and each pivoted at l one end to one of said llevers and at its opposite end to the fiat lug of the jaw pivoted to the other lever, said links being disposed at the outer sides of the lugs, a transverse punch or male die f'htting in the passage, ol'l said jaw, and a stein rigid. with the punch and extending rearwardly through and carried Aby the pivot of the levers.
